There is another category for PBS price for Prolia - Osteoporosis diagnosis AND had a fracture - you do not need to be over 70 in that event.Also recently discovered I have a 78 year old friend who is on Prolia for arthritis but as she does not have osteoporosis has to pay the NonPBS price.The overarching criteria is osteoporosis diagnosis and then either over 70 OR had a fracture.But bloody disappointing narrowness of criteria for PBS price nonetheless because of damage treatment does to bones and the medically acknowledged synergies of Prolia with Hormone Therapy to further reduce recurrence risk.
